Fractional Product Engineering

From an ambiguous idea to a product that ships.

I work with founders and small teams who know something needs to get built but not yet what, or in what order. I help you decide, design the system that supports it, and then build it — with one person accountable for how the whole thing fits together.

What I do

Five disciplines, one accountable partner

Engineering is the implementation, not the product. Point fixes rarely hold, so every engagement starts with what's worth building — and how the pieces work together once it is.

Discovery

Discovery, Roadmap & Systems Design

Most projects go wrong before any code is written. The wrong thing gets built, or the scope quietly triples. This is where we settle what to build, how the pieces should fit together, and what can wait.

  1. 1

    Frame the real problem

    Workshops with your team to separate the actual problem from the assumed solution.

  2. 2

    Cut scope to an MVP

    Prioritized requirements: what ships first, what waits, what gets dropped.

  3. 3

    Design the whole system first

    How the parts connect, where the data lives, what happens when something fails.

  4. 4

    Hand you the plan

    A phased roadmap with risks named — yours to act on, whether or not I build it.

  • MVP definition
  • Target-state design
  • Phased roadmap
Architect

Technical Architecture

Systems designed before implementation gets expensive. API and data design, scalability planning, and documentation your team can actually use.

  • System & API design
  • Scale planning
Build

Product Engineering

Production-quality software — applications, internal tools, dashboards, APIs. Architected to be extended for years, not rebuilt in eighteen months.

  • MVP builds
  • Modernization
Automate

Automation & Applied AI

Used only where it pays for itself: document processing, internal knowledge assistants, support triage, and the repetitive work eating your team's week. Every use case gets justified before it gets built.

  • Workflow automation
  • Internal tooling
  • Fewer manual steps
Partner

Fractional Product Engineering

A senior engineer and product partner on call — architecture reviews, roadmap refinement, and the technical decisions you don't want to make alone. Without the full-time hire.

  • Technical advisory
  • Team mentoring
  • Decision support

How it works

Every engagement starts the same way

No two products need the same thing, so nothing is packaged. Scope gets set once we both understand the problem — usually within a week of the first call.

    Discovery Call

    You describe the idea or the bottleneck. I tell you what I'd want to know before anyone commits budget.

    • No pitch deck, no obligation
    • A clear read on the biggest risk
    • An honest answer on whether I'm the right fit
    Start here
  2. 02Fixed scope

    Discovery & Roadmap

    Scope, architecture, and sequencing — the decisions that get expensive to reverse later.

    • An MVP defined and prioritized
    • A design for how it all connects
    • A plan that survives without me
  3. 03Scoped project

    Design & Build

    Delivery in phases, with one person accountable from first commit to launch.

    • Working software in weeks
    • Architected to grow, not to be replaced
    • Your team trained and handed the keys
  4. 04Retained

    Fractional Partnership

    I stay on as the senior technical voice as the product and the business evolve.

    • Architecture and code review
    • Roadmap and feature planning
    • A technical partner on call

Most clients start with discovery and keep going. You're never locked into the next stage.

Bring the idea you can't scope yet.

Thirty minutes, no pitch. You'll leave knowing the biggest risk in the project and what I'd do about it first.
